Frequently Asked Questions (FAQs)

Frequently Asked Questions About NBR Rubber O-Ring Factories in China

What are NBR O-Rings and what are they used for?

NBR O-Rings, also known as Nitrile or Buna-N O-Rings, are made from a copolymer of acrylonitrile and butadiene. They are widely used due to their good mechanical properties, abrasion resistance, and compatibility with fuels, oils, and solvents. You can find them in applications such as fuel tanks, lubricating oil tanks, and various fluid media like petroleum hydraulic oil and gasoline.

What is the temperature range for NBR O-Rings?

NBR O-Rings can operate within a temperature range of -40°C to 120°C (-40°F to 248°F). This makes them suitable for a variety of environments, although their low-temperature performance can be affected by the acrylonitrile content. Higher acrylonitrile content improves resistance to petrochemicals but reduces low-temperature flexibility.

What are the common specifications and sizes of NBR O-Rings?

NBR O-Rings come in various sizes and shapes, including round, square, and rectangular. The standard sizes follow AS 568, BS 1806, ISO 3601, DIN 3771, and JIS B 2401. The cross-section width ranges from 0.5 to 20 mm (0.020 to 0.787 inch), and the inside diameter can be as small as 0.7 mm (0.028 inch) or as large as 2965 mm (116.732 inch).

How do I choose the right hardness for my NBR O-Rings?

The hardness of NBR O-Rings is measured in Shore A units, typically ranging from 40 to 90. For most applications, a hardness of Shore A 70 is recommended. If the hardness is too low, the O-Ring may be prone to peeling and damage, while too high hardness can make installation difficult. You should choose the hardness based on the specific sealing pressure and application requirements.

What kind of chemical resistance do NBR O-Rings offer?

NBR O-Rings have excellent resistance to non-polar solvents such as fuels, oils, and gasoline, but they are not suitable for use in polar solvents like ketones, ozone, nitrobenzene, and chloroform. This makes them ideal for applications involving petroleum-based products but not for environments with polar chemicals. Always check the chemical compatibility before selecting an NBR O-Ring for your specific use.
